What is the difference between a cookie and a cache in Safari?
Jul 24, 2025 am 12:19 AMCookies and cache serve different purposes in Safari. 1. Cookies store user data like login info and preferences, enabling sites to recognize users across visits. 2. The cache stores temporary files such as images to speed up page loading on repeat visits. 3. Cookies can be managed or cleared individually under Safari’s Privacy settings. 4. Clearing the cache helps fix outdated pages, while clearing cookies resolves login issues. 5. Both can be selectively or fully removed to maintain smooth browsing performance.
When you're browsing the web on Safari, both cookies and cache help make your experience faster and smoother—but they do very different things. Here's a straightforward breakdown of how they work and why they matter.

What are cookies and what do they do?
Cookies are small bits of data that websites store on your device through Safari. They’re used mainly to remember who you are and keep track of your activity across visits.
- Login sessions – When you check "Remember me" on a site, cookies let it know it’s still you when you come back.
- Preferences – Sites use cookies to remember language settings, themes, or even items in your shopping cart.
- Tracking behavior – Ad networks also use cookies (third-party ones) to follow you around the web for targeted ads.
They’re tied directly to the website that created them, and you can manage them individually in Safari under “Preferences > Privacy.”

How is the cache different?
The cache is like a temporary storage locker for files your browser downloads—like images, scripts, or stylesheets. The main goal is speed: instead of downloading the same content every time you visit a site, Safari loads it from the cache.
- Repeats load much faster
- Reduces server load and bandwidth use
- Gets cleared automatically over time or manually when troubleshooting
Unlike cookies, cache doesn’t store personal info or login details—it just saves static files so pages appear quicker on repeat visits.

Why clear one but not the other?
Sometimes you’ll want to clear cookies without touching the cache—or vice versa. For example:
- If a site keeps logging you out unexpectedly → try clearing cookies.
- If a page looks broken or outdated → clear the cache to force fresh files.
You can choose which one to clear in Safari by going to “Preferences > Privacy” and clicking “Manage Website Data.” From there, you can remove cookies or cached files selectively or all at once.
Basically, cookies remember who you are, and the cache remembers what you saw. Keeping both in check helps Safari run more smoothly without unnecessary slowdowns or login hiccups.

Chrome's incognito browsing history cannot be viewed directly, but it can be obtained indirectly through three methods. 1. Use command line tools to view the DNS cache, which can only obtain some domain name information and is not durable; 2. Check the router or network monitoring log, which requires certain network knowledge and depends on network settings; 3. Install third-party monitoring tools and configure in advance to record invisible browsing behavior. Overall, the invisibility mode is designed to protect privacy. All the above methods have limitations. It is recommended to choose whether to use monitoring methods based on actual needs.

This setting only takes effect in the current session; 2. Specify the time zone through the command line startup parameters: close all Chrome instances and execute chrome.exe--timezone="target time zone" to affect the entire browser instance; 3. Use JavaScript to overwrite the behavior of the Date object, and the fixed time value is used to accurately control the JS time.
